Daer All,
I understand that EFA is using standarts limite of 9MB.
when i use send us a email with attachement bigger than 9MB they get this respond back.
Code: Select all
efa.domain.com
Remote Server returned '550 5.3.4 SMTPSEND.OverAdvertisedSize; message size exceeds fixed maximum size'
Does anyone knows how can we change the limite on the EFA?

edit /etc/postfix/main.cf and change the parameter message_size_limit to what you want the limit to be. (or include the parameter if it is not there)
message_size_limit = 20480000

Thank you for your answer
i managed to do this using the
Code: Select all
sudo postconf -e message_size_limit=50480000
sudo /etc/init.d/postfix restart
also for people who doesn't like the shell .
Also consider using the webadmin module under
Code: Select all
- servers
- Postfix Mail Server
- General Resource Control
- Max size of a message

first check current setting
try this with postconf or edit /etc/postfix/main.cf
# bump up the default messagessize limit: default message_size_limit = 10240000
# big mb limit
message_size_limit = 104857600
virtual_mailbox_limit = 0
mailbox_size_limit = 0

This looks like a Exchange warning (limited send connector?) and not EFA
